' THREAD-POSITIONER.

Patented Apr. 2, 1918.

Application filed September 1 3, 1916. Serial No. 119,953.

To all whom it may concern:

Be it known that I, ALoNzo E. RHOADES, a citizen of the United States, residing at Hopedale, county of Worcester, and State of Massachusetts, have invented an Improvement in Thread-Positioners, of which the following description, in connection With the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The present invention relates to filling replenishing looms, and more particularly to the means for positioning the'filling for the action of the filling parter.

In looms of the fceler type, wherein a fresh supply of filling is furnished prior to complete exhaustion of the filling, it is customary to provide means to part or sever the filling leading from the filling carrier to be abandoned close to the shuttle, and then carry the end of the filling leading from the cloth selvage into position to be severed later by the temple thread cutter. In practice it has been found convenient to mount the parting means, which parts the filling adjacent the shuttle, on the shuttlc-feeler or to otherwise arrange it that the parting means may be normally maintained in inoperative position and be moved to operative posit on only on call for filling re plenishment.

Since the filling leading from the filling carrier to be; abandoned extends from the cloth selvage to the shuttle-eye at the time the filling parter is moved to operative position, it frequently happens that the filling is not in proper position to be engaged by the parter. Sometimes it may be too high and sometimes too low to properly enter between the aws of the parter. This may be occasioned by slack filling between the cloth sel-. vage' andshuttle or by the lay movement or both. In any event, if the parter is' to perform its function it is essential that the filling be properly positioned for engagement by the parter. If the filling is too high for the action of the parter when the parter moves to operative position on call for filling replenishment, it should be'lowcred, and if too low it should be raised. Failure of the parter to act, usually results in the piece of filling leading from the cloth salvage to the shuttle, being carried into the shed on a pick of the shuttle after replenthe position of the filling and insure its engagement by the parting means. This feature of the invention, as one convenient practical form thereof, may be carried into efi'ect by causing the said members to move toward each other or in a direction of approach, so that if the filling is too high for the action of the--parter,.it will be lowered to proper position, or if too low it will be raised to such position,

Simplicity of structure and operation dictates that the filling positioning means be so devised and constructed that it shall not interfere with the action of the parter itself which, when it moves to operative position for performing its parting function, should find the filling already positioned for its action. Another important feature of the invention, therefore, consists in the association and combination of the positioning members and their operating connections so that on call for filling replenishment, soon after the shuttle has reached the. replenishing shuttle-box. the positioning members shall move to position the filling for the action of the parting means. This feature of the invention may be variously carried into effect, but in the form of the invention illustrated, the positioning members are mounted at the rear of the lay and project frontwardly across the raceway and are caused to be moved in the discharge of their positioning function when the feeler means or change shaft which is operatively connected therewith is moved responsive to a call for replenishment.

Various other features of the invention will be hereinafter described in addition to those noted and in connection with the ac companyin drawings, which illustrate one good practical form of the inver-ion, and the invention in its true scope, will then be defined by the claims.

In the drawings Figure 1 isa to or plan view of a portion of the loom clinnents, showing the filling parting means in operative position and the relation of the parting means and filling positioning means. i

Fig. 2 is an enlarged side elevation, showing the filling positioning means and its on erative relation to the associated parts, some portions of the-breast bean]. and lay being broken away, the two members of the positioning means being shown in the relation assumed by them upon cali for filling replenishment. 7

Fig. 3 is a View similar to that of Fig. 2, showing the normal position oi the positioning members during Weaving when the loom is running regularly.

Fig. 4 is a. detail: in perspective, showing certain features of the positioning means and their connections.

The loom frame and Weaving instrumentalities connected thereto may be of any ml'z-xzharaeter, as may likewise be the filia 62111 for replenishment to part or out it near the shuttle when the iattei' is in the replenishing shnttie box. it is now quite eeni- .mon to part the fitting near the shuttle, clamp the end leading from the cloth sel vage, and. then move the patter and clamp frontwerd to position the fiiling' for the ac tion oi a temple thread cutter. The partiew has and details of filling giaz'ter construction or the combined patter and cianip form no essential feature of the present invention, Which has to do more especially with the means for positioning the filling-f. extending between the cloth selvage and shuttle, for the-action oi? a filling pester regardless oi its detail construction.

In order, however, to make clear the present invention, andthe relation thereof with. the associated parts, l of the i -swings shows the lay 1, having the usuai shuttle-box 2, only one being partially indicated, the cloth 3, the temple 4 which may be provided with a temple thread cutter 5, the shuttle 6 in the box at the repiemshing side of the "loom and a filling patter 7 having the usual parting jaws 8 and 9. and a thread clamp 10. As above noted these parts may all he of usual construction, and as shown are or may be similar to the corresponding parts .in the patent to A. Clement, No. 641,?63,

dated Jan. 23, 1900, wherein, upon call for replenishment the patter and clamp are moved from a front or inoperative position toward the lay into an operative position to part andelamp the iillinqn t is usual. to associate the par-tea or the pater and clamp with the usuai shuttle-feeier, and if desired, this may be done'with the parter employed with. the present invention.

The invention contenipiates positioning; the filling between the cloth selvage and shuttle, so that may he engaged and ed. by the .-iiing parting means. the tilt paItQI' which acts upon the filling after h the positioning means will lower it, and it too low it Wilt raise it open call. for replenishment, se that; when the painter moved to operative position it will find the filling held in correct iocation ready for its action. To this end the positioning neans comprises two members normaiiy" the one at one side and the other at the other side of the path of the shuttle, so that dining weaving the filling will. he iaid between the two members, and should a eeil for i-epl meet scour, the two members will move towaix the position Whioh the Parts? Wiii occupy xvi 't moves into oper ative position, and so loeate the tilting, whether it he too high or ten ion, that the partei wili tinerringly and part it.

In the present instance of the invention, the members of the positioning means eomprise tii'zgeis i1 and 122 which extend from the of the la}; across the raceway, as indicated in that the shuttle, as

is elted to the replenishing; side of the loom (i ng Weaving may ay the filling between ti W0 ineinh 3.1 and 12. a convenient end, seoured, so that the norms? the iliustjiah and 4:, when permitted to do so. .Qhviousiy this arrangement, While siinpie, light and eiiieient, may be ehangedwithin the expected skiii of one famiiiat with the art.

H de sired a ped'i of leather er other'nommetai lie substance may he employed pon one side of the guide 17, and when used will be provided with the guiding slots 20 and 21, pref ei'ahly separated by an unslotted portion 22 to limit the closing movement of the mem bers it and 12. Since this pad he readily eheng'ed, the relation of the members 11 and 15B wl'ien in eiosed relation may obvionsiy be made to suit eontiitions ofnse. Mount d foo" ting "*zo'vei'nent between 7 separator for ers in separated )hvi'oiisly L" otaer. and halo.

apart by a separator, the reverse arrangemerit may be employed and s of course an equivalent.

- The separator, in the present instance of the invention, is preferably formed as a cam 23 connected to a shaft or stud. 24 mounted for rocking movement on the extension 14: of the bracket 13, and is located between the positioning members 11 and 12, the construction being such that when the separator or cani 23 is turned into the position Fig. 3, the members 11 and 12 will be separated, and they will be held separated for the passage of'a shuttle between them until the r separator or cam 23 is turned into the position indicated by Figs. 2 and a, whereupon the members 11 and 12 will move toward each other to either raise-or lower the filling laid between them by the shuttle, and position it" for the action of the parter.

The present invention in its preferred form contemplates, that the filling be positioned for the action of the parter upon call for replenislnnent, so that'when the parter reaches operative position it will find the filling in proper location. In the present instance the separator or cam 23 is operatively connected to the change-or transverse shaft, which upon indication of substantial Hip exhaustion of the filling is rocked in a manner and by the feeler means Well understood by those skilled in the art. To this end the "shaft 24: of the separator in the present instance of the invention has secured thereto a crank arm 25, which isjo'ined at 26 to an arm 27 pivoted at 23 to 'a controller-or arm 29. he arm 29 is pivoted at 30 to a bracket 31secured to the lay 1, and is providedwith a stop 32, which under the weight of the arts or in response to a spring, such as 33,

or both, normally restsupon the top edge portion of the-bracket 31,,the construction beingsuch that when the stop 32 is resting upon the bracket 31,21s in Fig. 3, the actuator 29 1s in lowered position and the separator or cam 23 is held, as in Fig. 3, with the positioning members 11 and 12 in normal separated. relation.

The breast beam 3 1, Fig. 2, has secured thereto sintable'supports, as 35 of usual and well known construction, for the change or itransverso shaft 36. Secured to the change ortransvcrse shaft IS an arm 37 provided or arm 29, and throughpermit the members 11 and 12 to move from their open or normal position, Fig. 3, to their more nearly closed relation, Figs. 2 and t to thereby locate the filling for the action of the parter.

After the filling has been replenished, and as the change shaft returns to initial position, the arm 37 is lowered again into its normal position, and the separator or cam 23 is again turned tocausethe members 11 and 12 to assume their separated relation and the stop 32 to rest upon the arm or bracket 31, substantially as indicated by Fig. 3.

Obviously other forms of connections and mechanical details will suggest themselves, as a means for controlling the positioning members 11 and 12 so as to present the filling for the action of the parter, but the form of the invention described has been found practical and simple, and while the spring action of the members is a convenient form of construction, they may be otherwise controlled.

In order that the lower member 12 may extend acrossthc path of the shuttle or cross the raceway without interfering" with the shuttle, the lay may be provided with a groove 39 into which the lower positioning member may extend below the shuttle path ,while the upper positioning member may project frontwardly above said path.
